TPMS Control Unit Replacement

NOTE: Make sure the TPMS control unit mounting bracket is not bent or twisted as this may affect its communication with the initiators and the tire pressure sensors.

Turn the ignition switch to LOCK (0).
Remove the gauge control module (see GAUGE CONTROL MODULE REPLACEMENT ).
Disconnect the TPMS control unit 20P connector (A).
NOTE: The TPMS control unit is located behind the gauge control module.

NOTE: To separate the TPMS control unit from the bracket, release the hook (D) on the TPMS control unit using a flat-tipped screwdriver (E), and push it up to remove the control unit from the bracket.
Install the new TPMS control unit in the reverse order of removal.
NOTE: Make sure the TPMS control unit is properly installed. You will hear a click when the TPMS control unit is securely mounted on the bracket.
Connect the HDS, and memorize the tire pressure sensor IDs (see MEMORIZING A TIRE PRESSURE SENSOR ID ). Do not memorize the IDs automatically.
